FIELD OF THE INVENTION

Embodiments of the invention generally relate to rubstrips with integral lighting for possible use in the interior of an aircraft.

BACKGROUND OF THE INVENTION

Aircraft interiors typically include rubstrips (sometimes referred to as bumpers) to help protect various surfaces inside the aircraft from damage. For instance, luggage and trolleys (galley carts) move up and down the aisles of an aircraft and are prone to bumping against seats or other surfaces in their path, which subjects such surfaces to paint chipping or other damage. As such, rubstrips are typically positioned along any surface in an aircraft interior that may be damaged or scratched if bumped from passing traffic. In some cases, the rubstrips are positioned along the trolley or other movable object. The interior surfaces where a rubstrip may be used to protect the surface from damage include, but are not limited to: entryways; doorways; closets; galley surfaces including counters; walls; seats; corners; baseboards; lavatory surfaces, etc. Although the rubstrips described herein are discussed for use in aircrafts, they are by no means so limited and may be used in any suitable environment, including without limitation buses, trains, other forms of transportation or any stationary structure or building.

In addition to the rubstrips, aircraft interiors include various lighting (for example, emergency lighting, area lighting, proximity lighting, ambient lighting, mood lighting etc.). Aircraft interior lighting is added for safety and function and also to enhance the passenger experience. Aircraft lighting has very specific requirements, which are different from requirements for providing lighting in other vehicles. Since lighting is susceptible to damage from luggage or trolleys, aircraft lighting is typically positioned away from trolley and luggage paths and is therefore restricted to particular locations within the aircraft. Because of the susceptibility to damage and the limited placement of aircraft lighting, lighting in aircrafts is provided by a device that is separate from the rubstrip. Design complexity and weight of the aircraft are increased due to the multiple parts and assemblies for the lights and separate rubstrips.

DETAILED DESCRIPTION OF THE DRAWINGS

The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.

Disclosed herein are rubstrips with integral lighting. The rubstrips are configured to protect various exposed surfaces from damage and are also configured to protect the light source from damage. As shown in FIG. 1, rubstrip 10 includes at least one passageway 12 from which light from the light source may be emitted. The at least one passageway 12 may be positioned in any suitable manner along an exterior of the rubstrip 10. Although the at least one passageway 12 is illustrated in the Figures as positioned toward the center of the rubstip 10, the at least one passageway 12 may be offset or positioned in any suitable location along the rubstrip 10. The positioning of the at least one passageway 12 may be selected based on the configuration of the surface with which the rubstrip 10 will be used and/or the desired direction of the light to be emitted from the rubstrip 10. The at least one passageway 12 may have any suitable dimensions and may be shorter/longer and/or wider/narrower than the embodiment illustrated in FIG. 1.

In some embodiments, the at least one passageway is a transparent or semitransparent surface of the rubstrip that allows light to be emitted through that portion of the surface of the rubstrip. In some embodiments, the at least one passageway 12 may be a cutaway portion of the rubstrip, or it may be a groove or other opening. In some embodiments, the at least one passageway 12 optionally may be covered by a transparent or semi-transparent cover.

Positioned within an interior of the rubstrip 10 is a light source 14. In some embodiments, light source 14 is positioned within the rubstrip 10 such that the rubstrip protects the light source 14 from damage. Light source 14 may be oriented within rubstrip 10 so that light source 14 aligns with the at least one passageway 12. In this way, light emitted from the light source 14 can also be emitted through the at least one passageway 12 and out the exterior of the rubstrip 10.

Light source 14 may be one or more standard light sources (e.g., but not limited to, a single source LED emitted through a clear rod, continuous lighting, an electroluminescent wire, a fluorescent bulb, an incandescent bulb, an arc lamp, one or more LEDs, or any other suitable light source). Another non-limiting example of a suitable light source is a molded silicone encapsulated light sold by Dow Corning. In some cases, the light source is flexible so it can be used along curved surfaces, as shown in FIGS. 4-5, although it need not be.

Rubstrip 10 may optionally include one or more end caps 20, as shown in FIG. 1, to cover the ends of the rubstrip 10. As shown in FIG. 2, rubstrip 10 may also include a base 24 to assist with mounting of the rubstrip along the surface and/or to provide support to the rubstrip 10 and/or the light source 14. Rubstrip 10 may also include a retainer assembly 22 configured to help retain the internal parts of the rubstrip, including the light source 14.

Rubstrip 10 may optionally include a light channel 26. If used, light channel 26 helps direct and modify the light by reflecting, deflecting, and/or diffusing the light emitted from light source 14. In some embodiments, a diffuser, such as diffuser 16 shown in FIG. 3, may be positioned within the rubstrip adjacent the light source 14 to diffuse light from light source 14.

Rubstrip 10 may be formed of plastic or any other suitable shock absorbing or resistant material. In some embodiments, the base or other components of the rubstrip may be formed of metal or composite materials. In some embodiments, rubstrip 10 is formed by extrusion, injection molding, thermal formation, machine formation or any other suitable process. After rubstrip 10 is formed by any suitable process, light source 14 may be assembled with rubstrip 10. In some embodiments, light source 14 is positioned within the interior of the rubstrip 10 through one of the ends of the rubstrip. In other embodiments, light source 14 is positioned within the interior of the rubstrip through the at least one passageway 12.

In some embodiments, light source 14 is powered by any suitable existing power source. The rubstrip may be configured to cover and protect any desired surface, such as, but not limited to, walls, baseboards, counters, doorways, entryways, corners, or any desired surface, including but not limited to surfaces associated with seats, lavatories, galleys, trolleys, etc. If used in an aircraft, rubstrip 10 may be positioned along any suitable surface, such as aisle entrance 18 as shown in FIGS. 4-5 or a seat as shown in FIG. 6. As mentioned above, the rubstrip is not limited for use in aircrafts, but may be used in any suitable interior or external surface.

The illuminated rubstrips described herein have a dual purpose of protecting a surface from damage and also protecting the rubstrip's integral light source from damage. Providing a single device that serves as a light source and that protects various aircraft internal surfaces from damage, as well as protects the light source itself from damage, results in cost savings in production and also reduces the overall weight of the aircraft. Because the rubstrip is capable of emitting light, it also satisfies various aircraft lighting requirements.

The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of the present invention. Further modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of the invention. Different arrangements of the components depicted in the drawings or described above, as well as components and steps not shown or described are possible. Similarly, some features and subcombinations are useful and may be employed without reference to other features and subcombinations. Embodiments of the invention have been described for illustrative and not restrictive purposes, and alternative embodiments will become apparent to readers of this patent. Accordingly, the present invention is not limited to the embodiments described above or depicted in the drawings, and various embodiments and modifications can be made without departing from the scope of the claims below.
